Catalog Number - 9502S-E-10C-R-M

Soft‑Guard™ septa are engineered to reduce needle resistance while maintaining consistent resealing, helping improve injection reliability and reduce downtime.

The 9502S‑E‑10C‑R‑M Soft‑Guard™ Screw Caps utilize a specialized silicone formulation that minimizes coring and maintains elasticity across repeated injections. The bonded PTFE/silicone septa provide chemical resistance and protect sample integrity in HPLC, GC, LC‑MS, and GC‑MS applications.

The red polypropylene cap offers easy visual identification and features a knurled exterior for secure handling and consistent torque. Designed for standard 9‑425 thread, 12 × 32 mm autosampler vials, these caps are well suited for high-volume laboratory environments.
